Swans Island's mill is one of only 4 in the United States that has a Global Organic Textile Standards certification. That means that the mill must be inspected and must conform to certain criteria to be considered organic. What this means in layman?s terms is that less harsh chemicals are used in processing, thus helping the yarn retain more natural lanolin than many other commercially produced yarns. Swans Island extra fine merino is soft enough to wear next to your skin. After knitting and blocking, your finished projects will bloom to have a beautiful soft luster and a wonderful feel. Swans Island 100% certified organic merino wool is an inspiration. The hues are achieved by using only natural dyestuffs, resulting in beautiful yarns with lots of variegation.
